Removing disk passthrough

Good afternoon,
I initially set up a VM with mergerfs and samba on it. I formatted the disks directly on the VM. I'd like to redo that and have proxmox handle the harddrive mounts directly and run a lxc container with samba and another with mergerfs.

The problem is that I cannot seem to get proxmox to see the hardrives as available again.

I set the passthrough initially with
Code:
qm set  102 -  -scsi2 /dev/disk/by-id/device
I have tried removing it with
Code:
qm set  102 --delete scsi2
When I try to now mount it under disks, I just receive a message saying no unused disks. Shouldn't the hard drive I detached now be availble?

On this thread, it stated they had to reformat all the drives. I'm really hoping that's not the case.

I was able to manually mount the drives directly on proxmox so I know they are mountable.

Is the problem that I am using ext4? I just read through the storage section and I don't see that listed (unless it's covered under directory).
Edit - it's covered my directory.

Short of reinstalling and loading all the drives at start, is there a way to have proxmox see these drives? I'd rather reinstall proxmox than copy 14 tb all over again.

You could manually mount the drive using fstab. If you create a disk using the WebUI it wants a clean drive because it will format it.
 
I didn't do it through the webui (I didn't realize I could when I was setting this all up.)

I've tried removing the drive from the VM using the webui and from the CL. Neither let's proxmox see it.

I don't mind adding it directly to the fstab but I believe that would mean that I won't be able to administer it via proxmox. I'm switching to LXC so that I can better use the tools.
